Filed: 1916-07-31
Abstract: 101,095. Rogozea, S. July 31, 1915, [Convention date]. Void [Published under Sect. 91 of the Act]. Barrels; recoil, modifying.-Relates to projectiles, of larger diameter than the barrel bore, adapted to be attached to, and fired from, the muzzle of a small-arm, and to muzzle attachments for use when firing such projectiles. According to the invention, the projectile has a tubular tail adapted to fit outside the barrel or barrel extension, and a cartridge containing a pro. pelling-charge adapted to fit inside the bore, and on the outside of the barrel or extension is a swelling at the muzzle adapted to act in conjunction with the tail of the projectile to reduce recoil. In the constructions shown in Figs. 1 and 2, the barrel 1 of the gun carries an extension 2 which is formed on the outside with a series of notches 14 and a conical swelling 3 at the muzzle. The projectile has a tubular tail 7 fitting over the extension 2 and split at the end to form inturned claws 13, which can be compressed to engage one of the notches 14 by a sliding ring 9. The projectile also carries a cartridge 17 fitting inside the extension 2. In the construction shown in Fig. 1, the cartridge has a cap 20 and a striker 22 adapted to be actuated bv the gases from a cartridge in the gun barrel. In the construction shown in Fig. 2, the cap 20 of the cartridge is exploded by a firing-pin 36 mounted in the barrel extension 2 and actuated bv the gases of a cartridge in the gun barrel, the gases in this case escaping from the barrel through a small hole 35. When the cartridge is fired, the claws 13 are forced out of the notches 14 and. on meeting the enlargement 3, exert a forward drag on the gun, which reduces recoil. The projectile shown in Fig. 1 contains an explosive charge 30 which is exploded either by a percussion cap 31 or by a time-fuse 32 at the base. The cap is protected by a hood 33 of waterproof fabric and a cover 34, which will be removed before firing. The projectile shown in Fig. 2 has a charge 27 of fusing, illuminating, or asphyxiating material which is ignited by a fuse 28, the products of combustion escaping through openings 29.

Filed: 1946-04-08
Abstract: 610,499. Door -operating mechanism. LONDON PASSENGER TRANSPORT BOARD, TAYLOR, J., and GILES, C. H. J. April 8, 1946, No. 10816. [Class 65 (i)] [Also in Group XXXII] A sliding door for a passenger vehicle comprises two leaves 14, 15, Fig. 1, adapted to move together as a unit until the leaf 14 covers, for example, a fixed part 13, whereupon a trip mechanism 26, Figs. 2, 4, connecting the leaves 14, 15 is released and the leaf 15 moves independently over the leaf 14. The leaf 15, Figs. 2, 4, is suspended from a channel rail 16 by brackets 23, 24 having rollers 18 guided in the channel and the leaf 14 is similarly suspended in a channel 17 by brackets 21, 22 and spaced from the channel 16. The trip mechanism 26 comprises a Y-shaped bracket pivoted at its centre to a pivot on the bracket 22 and biassed with the stem downwards by a spring 27, Fig. 4. Each arm of the Y-shaped bracket is provided with a roller 33 which runs on a short length of' track 34 attached to the rail 16, one of the rollers running off the end of the track in either the open or closed position of the door. In the closed position of the leaves, Fig. 2, one roller of the trip contacts the track 34 and the stem 28, which has been brought into the vertical position by the spring 27, is spaced a distance x from a buffer 35 on the leaf 15. When the leaf 15 is moved to the left by a rod 25 either manually or pneumatically, the buffer 35 contacts the stem 28 of the trip, whereby the leaves 14, 15 move as a unit until the other roller 33 of the trip clears the end of the track 34, the trip then rocking about its pivot to permit the stem 28 to clear the buffer 35. This action disconnects the leaf 14 from the leaf 15 and allows the leaf 15 to continue its movement across the leaf 14, the stem 28 riding on the top edge 37 of the leaf 15 until it clears the end, whereupon the spring 27 moves the stem into the vertical position for engagement by a buffer 36 on the opposite side of the leaf to the buffer 35. In this position the door is finally open and the trip in position to actuate the leaf 14 on movement of the leaf 15 towards the closed position.

Abstract: 1421432 Matrix displays and circuits therefor FUJITSU Ltd 7 March 1973 [8 March 1972] 11219/73 Heading G5C A method of operating a gas discharge display/memory panel 1 comprises controlling logic circuitry 2, 3, through which sustain voltages are applied, (a) to discontinue the sustain voltage before the output voltage of the power supply 8 falls significantly when mains power is cut off and (b) to delay application of the sustain voltage until the output voltage of the power supply reaches a steady state when mains power is switched on. This method reduces transient phenomena during starting and stopping operations thereby extending the time that wall charge patterns can be retained and also increasing the speed at which discharges are established. A voltage pen can be used to erase wall charges when the mains are off. Mains voltage is supplied through switch 10 to H.T. and L.T. power supplies 8, 9 and a control signal is applied through switch 11 to logic circuit 7 which controls gate circuits 2, 3. Opening switches 11 then 10 stops the sustain voltage before the output from supply 8 falls significantly. Closing switches 10 then 11 applies the sustain voltage only when the output reaches the steady state. Switch 11 may be replaced by a circuit including a high speed detector and a delay circuit.

Title: Circuit arrangement for processing pulses
IPC: G01R23/02
Filed: 1978-03-22
Abstract: On the one hand, a charging/discharging-type store (1) is provided which is recharged at the rate of the pulses from an initial voltage value to final voltage values which differ from the initial value, the final voltage values representing a measure of the pulse spacing. Furthermore, a comparator is provided which compares whether the measured pulse spacing is within a permissible range of fluctuation and which in each case forwards measured pulse spacing to a device for further processing and/or display when the latter situation holds true. Two stores (15, 16) of a plurality of individual stores for the final voltage values of the charging/discharging-type store (1) are connected to a comparison element (18). The latter closes a transit gate (3) if compared storage values are within a permissible range of fluctuation. The gate, which is used for directly or indirectly switching through further final voltage values to the two comparison stores and remaining individual stores (11 to 14) for further processing of the voltage values is only opened again shortly after a time interval which corresponds to the pulse spacing which has previously been detected by the comparator stores (15, 16) as pulse spacing which is correctly within the range of fluctuation. The circuit arrangement is particularly used in foetal heart rate measurement in accordance with the ultrasonic doppler principle. <IMAGE>
